It is preferable to use a lint-free cloth (the kind used to clean glasses, etc.). They should be easy to find.

If you want to go the extra mile, you could use the kind of spray used to clean LCD monitors.

Yikes, I don't think there is. Did you try pulling of the protective cover (if there was one)?

The same thing happened to my DS phat. For some reason the stylus screwed up (after I had been using it for days) and scratched up the screen; I sold the DS on eBay shortly afterwards, hehe.

I was actually using an official Nintendo stylus too, although it was a larger pen stylus; needless to say, I threw that crap in the trash shortly afterward... I was ticked.

I'll be getting an DS (black/onyx) soon and plan on putting screen protectors right away. Oh well--live and learn.

I would go with SSX Blur. Like others have said, the control scheme does take some getting used to though. At first, I hated it, but now that I've got the hang of the controls, it's awesome. In my opinion, there is a ton of replay value for this game, online or not.

I have not had any first-hand experience with Godfather, but it seems like it could be cool as well. I'm just giving my opinion; it's up to you. If you're really on the fence, just rent one or both of the games. 

Man, that was sweeet. Nice job!

Actually I really liked the Milk Bar theme, heh. Relaxing.
